Everyone here is being so helpful and nice to the OP with suggestions that the error is from condensation, Low sun angle, Change in temperature, etc... and it should eventually go away. To me this seems like polite excuses for bad engineering. Do you think the astronauts at Space X say, "Don't worry about the error message, go ahead and launch it's just condensation"? I don't think so! Tesla needs to sort this stuff out before the car goes into production and not have customers beta test failed systems. I doubt the SC has a solution.
